Age spots—also known as liver spots or solar lentigines—are flat, darkened patches that appear on the skin due to long-term sun exposure and natural aging. They are common on the face, hands, épaules, and arms, especially in adults over 40.
With the rise of non-invasive skincare technologies, many people are asking: Can red light therapy help with age spots?
La réponse courte: red light therapy does not directly remove age spots, mais ça peut support overall skin tone, texture, and clarity, making age spots appear less noticeable over time.
What Causes Age Spots?
Age spots form when excess melanin accumulates in certain areas of the skin. Contributing factors include:
- Chronic UV exposure
- Slower skin cell turnover with age
- Oxidative stress
- Reduced collagen production
Because age spots are pigment-related, treatments typically target melanin or skin renewal.
Qu'est-ce que la thérapie rouge?
Thérapie par la lumière rouge, également connue sous le nom de photobiomodulation (PBM), uses low-level red and near-infrared wavelengths—usually between 630 nm et 880 nm—to stimulate cellular activity in the skin.
Unlike UV or IPL treatments, red light therapy is non-ablative and does not damage the skin surface. It is widely used for skin rejuvenation, réduction des rides, and inflammation control.
How Red Light Therapy May Help Improve the Appearance of Age Spots
While red light therapy does not bleach or remove pigment, it may help age spots in several indirect ways:
1. Supports Collagen and Skin Renewal
Red light therapy may stimulate fibroblasts to produce more collagen, improving skin thickness and elasticity. Healthier skin can make pigment irregularities appear softer and less pronounced.
2. Promotes More Even Skin Tone
By supporting circulation and cellular repair, red light therapy may contribute to a more uniform complexion over time.
3. Reduces Inflammation and Oxidative Stress
Inflammation and oxidative damage can worsen hyperpigmentation. Red light therapy may help calm the skin environment that contributes to uneven tone.
4. Enhances Skin Healing After Pigment Treatments
Red light therapy is often used after treatments like chemical peels or laser therapy to support healing and reduce downtime.
Que dit la science?
Research shows that red light therapy can:
- Improve skin texture and firmness
- Reduce fine lines and wrinkles
- Support wound healing and cellular regeneration
Cependant, direct evidence showing red light therapy alone can eliminate age spots is limited. Pigment-targeting treatments such as IPL, thérapie au laser, or topical brightening agents remain more effective for spot removal.
Red Light Therapy vs Pigment-Focused Treatments
| Traitement | Primary Effect |
|---|---|
| Thérapie par la lumière rouge | Rajeunissement de la peau, tone support |
| IPL / Laser | Targets excess melanin |
| Chemical Peels | Accelerates skin turnover |
| Topical Brighteners | Inhibit melanin production |
Red light therapy works best as a supportive skincare technology, not a pigment-erasing solution.
How Red Light Therapy Is Typically Used for Skin Rejuvenation
Common skincare-focused protocols include:
- Longueurs d'onde: 630–660 nm (feu rouge)
- Durée de la séance: 10–20 minutes
- Fréquence: 3–5 fois par semaine
- Application Areas: Affronter, hands, poitrine
Results are gradual and typically become noticeable after several weeks of consistent use.
Safety and Expectations
Red light therapy is generally well tolerated and suitable for most skin types. Toujours:
- It should not replace sun protection or medical pigment treatments
- Consistent sunscreen use is essential to prevent new age spots
- Individuals with active skin conditions should consult a professional
